If you use the gnome lot trait, the gnomes repair all appliances at about 3 in the morning. So far, my child alone hasn't broken anything. It is just adults that break my stuff.
If you are eating your dinner at the university, the students will help you learn to ride a bike and will help you do your projects.
Eating the grand meals at the university works, but I have not been able to do anything there about Christmas presents. A child alone can GIVE Christmas presents though and can ask Father Winter for a present. Children are prefectly happy with this.
No adults have turned over a dumpster, so far. If you leave out broken things that are found in the dumpster, the gnomes fix them overnight, but do not clean them.
If you use the dollhouse, you can write a children's book afterwards. Even with mods, I have not been able to publish the book though. Only with mods can you build the writing skill. Even with mods, I have not been able to build the writing skill with any kind of notebook, or use it to write the book. A computer is needed to write the book.
ClaudiaSharon mod Kids can Gain Painting and Writing Skills. My child was only able to gain writing skills with books and a computer. She wrote a bestseller after multiple tries, but could only get $250 if she sold it.

Children can harvest plants and replant, water, and weed them with a level 6 mental skill, but cannot build gardening skill without a mod. My goal is to build the mental skill level high enough to take advantage of the first Spice festival and Romance Festival harvestables. I use 14 day seasons, so can sometimes get one or two harvests of my own before the season changes. I prefer to use the birds rather than the scarecrow to keep the bugs under control. Children cannot spray for bugs. Sometimes I just plant a plant, knowing that I will only get two harvests before it dies from bugs.
If you are going to use mods, you can hang the fork food spawner behind the bars, so that children can get free food there.

There is a mod that makes a cooler store food, but if the repo man takes the cooler, some the mod is left behind and things get weird.

I think this might be the link to the cooking mod that I liked best. The Zulf mod has less stretching than the sparklimari mod, at least for me.

The Zerbu All worlds are Residential mod allows children to travel alone to Granita falls and meet the Hermit and catch bugs and harvest the herbs.
There are some mods that allow you to add more scars to children.
Ilkavelle and BossladyTV have aspiration mods for kids.
